Kutno Operational Group
Kutno Operational Group, named after the town and major rail junction of Kutno,, was an Operational Group of the Polish Army, created in March 1939, a few months before the Invasion of Poland. Its official name was Kutno Reserve Group of Commander-in-Chief, and it remained under direct control of Commander-in-chief of the Polish Army, Marshal Edward Smigly-Rydz.
According to Plan West, the Kutno Reserve Group, consisting of three infantry divisions, was to be concentrated in the area of Kutno, Wloclawek, and Plock. As Colonel Jozef Jaklicz of Polish Army headquarters specified, the group was tasked with the following:
- defence of the Vistula river line, between Pomorze Army and Modlin Army,
- protection of flanks of Poznan Army or Pomorze Army.
In the evening of August 27, 1939, some regiments of the 5th Infantry Division were mobilized. By Sunday, September 3, the regiments arrived at the Kutno rail station, and on the next day they reached Wloclawek, where they were incorporated into Pomorze Army, as the so-called Detachment of Colonel Sadowski. These regiments were the only units of the projected Kutno Operational Group, which reached the concentration area.
Due to worsening situation of the Polish Army, which was forced into a general retreat, on September 3 Polish Commander in Chief, Marshal Edward Smigly-Rydz abandoned the idea of creation of the Kutno Group. On that day, 24th Infantry Division was transferred to Karpaty Army, and on September 4, the 5th I.D. was transferred to Modlin Army.
